The question is a reasonable one: electric cars may be zero-emission, but what about the electricity to recharge them? While renewable energy is growing globally, burning fossil fuels is still the source of most electric power today. The good news is that in most areas of the U.S., the "wells to...

The Volkswagen diesel scandal left lasting imprints on the entire automotive industry, and may have changed the way regulators look at vehicles using the fuel forever. That's true not just in the United States, but elsewhere as well. The European Union is now increasing its efforts to make sure a...

In the wake of its diesel emission scandal, Volkswagen has done its best to portray itself as a cleaner, more thoughtful automaker. Part of the damage control plot includes a slew of new electric vehicles to round out the German automaker's portfolio in the coming years. But, what about the...

During President Donald J. Trump's half-hour meeting with Pope Francis at the Vatican yesterday, the pope gave the president a copy of his 2015 encyclical calling for urgent, drastic cuts in fossil-fuel emissions. It is unclear whether the U.S. president will peruse the document. Back at home...

The U.S. Justice Department sued Fiat Chrysler Automobiles yesterday over allegations that diesel engines in its light-duty trucks included equipment to defeat Environmental Protection Agency emissions tests. First reported as impending last week, the suit alleges that FCA fitted up to eight...

While the news headlines on President Donald Trump mostly address potential scandals, his administration has also lagged significantly in appointing top-level officials to run government agencies. Those that have been appointed often have an adversarial relationship to the missions of the agencies...

California has by far the most aggressive climate-change policies in the nation, and the state is a global leader in plans to reduce carbon-dioxide emissions. It's also the world's eighth-largest economy, with a growing population, soaring economic output, and a resolutely progressive legislature...

Much of the news out of Washington, D.C., these days has to do with the possibility of political scandal. But the wheels of government keep turning, and significant changes are happening at numerous agencies charged with missions as diverse as collecting intelligence, supporting education, and...

When a major lobbying group issues a statement replying to an academic study the same day that study first hits the media, you know it's major. On Monday, the Diesel Technology Forum responded to an article in Nature with a statement that supported "improved real-world testing" of diesel emissions...

Today's political climate has made for fluid motion in regulations, and corporate average fuel economy targets haven't been left out. Suppliers and automakers have already begun investing heavily into vehicles to be sold in 2022 through 2025, which will include various fuel-saving and...

California began regulating vehicle emissions within its boundaries before the Environmental Protection Agency was even a gleam in President Richard Nixon's eye. Since that agency was founded in 1971 with an executive order by Nixon, the state has retained the right to set its own—more...

Anniversaries often provide an opportunity to reflect on important past events, review what has happened since, and reflect upon the future. April 2 of this year marks the 10th anniversary of the Supreme Court ruling in Massachusetts vs EPA in which the EPA was forced to regulate carbon emissions...

While much of the nation's capital is preoccupied with the unpredictable Trump administration and its possible ties to Russia, the fate of the Environmental Protection Agency generates less news coverage. That's not to say there hasn't been news. Administrator Scott Pruitt is proceeding swiftly...

It's now clear that the zero-emission vehicles of the future will be powered by electric motors. The electricity to power those motors, however, will come from one of two competing technologies: high-capacity batteries or hydrogen fuel cells. The debate over which technology is superior, which has...

Barbie never said "Math is hard!" The talking doll did, notoriously, say "Math class is tough!" in 1989, sparking a media firestorm over gender roles in childrens' toys and then a voluntary recall by Mattel for offended parents. Reworded, however, the point remains accurate: many people don't...

It has become increasingly more evident that carmakers must take aggressive steps to ensure that diesel cars and light trucks meet current environmental regulations. Tests done by Emissions Analytics found that the majority of new diesel-powered cars sold in Europe do not meet the Euro 6 emission...

Advocates have long suggested that electric vehicles will begin to take over daily driving duties, slowly but surely, from the internal-combustion engine. Now, even oil companies are starting to acknowledge that there may be reality in that dream of the future. France's Total SA, one of the world's...

The current EPA administrator, Scott Pruitt, does not accept the scientific consensus on human contribution to climate change, though he has given some contradictory statements on that matter. His views correspond closely to those of his boss, President Donald Trump, who notoriously compared the...

The Industrial Revolution that started around 1750 in England was powered largely by coal. With Watt's invention of the steam engine and the emergence of railways in the mid-nineteenth century, the carbon-dense fuel was central to the change from an agricultural economy to an industrial one. Last...

As the Trump Administration nears its 100th day, it seems fair to say that it is still emitting mixed messages on multiple issues, from foreign policy to climate change. On that latter, it's important to reiterate that the president and many of his appointed agency and department heads deny the...
